Electric Arc Furnace
Innovating NIKKO's Electric Arc Furnace through Unique Technology.
NIKKO achieved an optimal combination of furnace diameter, electrode PCD, and transformer capacity and strengthened the lifting and swing of the furnace roof, electrode lifting, and the tilting speed of the furnace body to promote efficient melting in NIKKO's unique electric arc furnace.
Furthermore, the design of each part has been made as simple as possible to improve maintainability.
In addition, the furnace volume was made one size larger than that with conventional models to reduce the scrap charging time and scrap pressing work.
The furnace is equipped with an aluminum conductor developed /designed by NIKKO which has the features long arcing by reducing the reactance of the secondary conductor on the furnace side.
